ROYAL RUEBEN MILLER, 01? PUEBLO, COLORADO.

ADJUSTMENT FOR INVALIDS COTS.

To all whom 2'25 may concern Be it known that I, ROYAL RUEBEN MIL- LER, a citizen of the United States, residing at Pueblo, Colorado, have invented certain new and useful Improvements in Adjustments for Invalids Cots, of which the following is a specification.

My invention relates to improvements in adjustments for invalid cots, and has for its objects the lifting, tilting, and conveyance of invalid cots superimposed upon the usual mattress of a bed and the transporting of the occupant from place to place, by means of this invention, as well as other objects which will more fully appear in this specification. I attain these objects by the mechanisms illustratedin the accompanying drawings, in which Figure 1 is a front elevation view; Fig. 2 is an end elevation designated as the foot; Fig. 3 is a perspective view showing-the device in connection with an invalid cot, and as applied to the cot and bed; Fig. 4 is a perspective view of the upper part of the device in broken section showing the interior arrangement of the pulleys, cable and elevating screw; Fig. 5 is a detail sectional view showing the position of the screw threaded bar in the tube and means for preventing the turning of the nut; Fig. 6 is a broken sectional view showing the interior arrangement of the screw threaded bar and one of the cables; Fig. 7 is a top plan view of the tube containing the screw threaded bar; and Fig. 8 is a detail drawing of the adjusting means for turning the screw threaded bar.

Similar numerals refer to similar parts throughout the several drawings.

At each end of the device a crane construction is provided by upright tubes 1 and 2 at the head end joined by the coupling 18, with the overhanging arm 6 provided with the brace 31, and the base piece 12 provided with braces 14, 15, and 16 to aid in rigidity, and the tension bar 46 to strengthen the construction. The foot or lower end is constructed in similar manner,the upright consisting of tubes 17, and 20 joined by the coupling 19, with overhanging arm 22, and base piece 30, with braces 24, 25, 26, and 27 to aid in rigidity as Well as tension bar 29 to strengthen the construction atthe point where one of the heavy strains occurs on the uprights. The horizontal tube composed of parts 8 joined by the union 9 is attached to Specification of Letters Patent.

the foot and head pieces approximately midway of the perpendicular tubes and carries a cable. The tube 10, in two parts, is joined by union 11 and is attached to the uprights near the base of each respectively by appropriate unions. Casters 13 are provided. In one of the uprights, preferably at the head, the bar 33, provided with a squared head 32 extending above the horizontal upper arm, is centrally disposed in the tubes 2 and l with the portion 34, below the union 18, screw threaded. In the tube 1 a slot 37 is provided. A nut 35, operative on the screw threaded portion 34, is provided with a pin or boss 36 adapted to operate in the slot 37. One end of the cable 38 is attachedto the nut 35 and passes upwardly through the tubes 1 and 2 over the pulley 5 and over the pulley 7 in the end of arm 6; and at the end of the cable 38 appropriate ends are provided for attaching to the end of the invalid cot 43. One end of another cable 39 is attached to the nut 35, passes up into union on tubes 1 and 2, over pulley 40, along the interior of the tube 8, over the pulley 41 disposed in the union 19, through the interior of the upright tube 20, over the pulley 42 disposed in the union 21, through the interior of the arm 22 and over the pulley 23 in the outer end of the arm' 22, and the cable 39 is also provided with means for attaching to the lower end of the invalid cot 43. While I have provided slotted means 37 in which the pin or boss may operate to prevent the turning of the nut 35, it is plain to be seen that other means of construction may be used to obtain this result without departing from the principle of my invention as the tube may be square or any form other than round so as to prevent the turning of the nut therein.

In the event that it is necessary or desirable to operate the device by perpendicular rotation of the crank 46 instead of by horizontal rotation means, I have provided the crank gear wheel construction 44 in housing to receive the square head 32 of the rod 33 and the squared head 45 on the perpendicular gear for attaching the crank. This gear means may be set on or off at the discretion of the operator.

The device being assembled, as shown in Figs. 1 and 3 it may be pushed up to a bed 50 so that the feet 12 and 30 reach under the bed and the cranes 6 and 22 are over the bed. WVhen the cables 38 and 39, by attaching means, may be connected to the superi1nposed invalid cot as, and upon applying the crank 46 to the head 32 of the bar 33 and operating the same, the nut 35 would be driven down and by the cable means as be tore stated the invalid cot 43 would be lifted free from the bed 50, or either end; thereof could be lifted or the invalid cot could be elevated by the device and the occupant transported by the device, from place to place.

While I have shown braces to the main parts of the construction for the purpose of securing the greatest amount of rigidity, other braces could be added thereto or arranged Without departing from the prin- .ciple of my invention. In fact in construe tion it Would be preferable to add a brace from upright 2 to tube 8, and from upright 20 to tube 8 as I have done in actual coiistruction, and each upright tube at each end may be madein one part with slots for the pulleys and to permit the cable to pass through the side tube 8;.

I am aware that elevating devices have been invented and constructed as applied to invalid and hospital beds and cots, and I do With casters the Whole suitably braced; a

crank; and a screw threaded bar disposed centrally in one of the upright portions of the crane construction; a nut on said screw threaded bar provided with a boss adapted to engage a slot in the tube inclosing said screw threaded bar; a slot in the upright tube containing said screw threaded bar adapted to receive the said boss on said nut;

cables attached to said nut conducted on the interior of the tubing construction by pulley means at every angle, one to the exterior end of each of said overhanging arms, all

substantially as set forth.
